I think you might have made an error. If I recall correctly, it was Henry I (the Conqueror’s youngest son) who was involved in the blinding of his granddaughters. Henry I was not, however, a Plantagenet king. The first of that dynasty was his grandson, Henry II. And in his partial defense, he did not order the blinding, only condoned it. His granddaughters had been exchanged by his son-in-law has hostages. His son in law then blinded and mutilitated his hostage. The father of the mutiliated girl retaliated by blinding his hostages (Henry I’s granddaughters), but only after obtaining Henry I’s consent or at least non-objection. Presumably, Henry I viewed his son in law’s actions as being out side the pale and refused to exempt his grandchildren from the consequences of their father’s folly. Coinncidentally, Henry I allegedly had his elder brother, Robert, blinded after a failed escape attempt. All in all, a pretty atrocious family to belong to. Steve Moss
